Este trabalho apresenta a composição funcional (CF) como um novo paradigma para realização da síntese lógica de blocos combinacionais. CF usa uma abordagem ascendente para sintetizar funções Booleanas, sendo capaz de avaliar os custos das funções intermediárias e explorando dessa forma um grande número de combinações diferentes de funções candidatas. Há vantagens interessantes quando comparado à abordagem descendente da decomposição funcional. CF apresenta grande flexibilidade para criar algoritmos com resultados ótimos ou subótimos para diferentes aplicações. A estratégia proposta apresenta bons resultados para síntese de funções Booleanas visando diferentes tecnologias. CF é baseado nos seguintes princípios: (1) representação de funções lógicas como um par ligado com representações funcional e estrutural; (2) o algoritmo começa de um conjunto de funções iniciais; (3) funções mais simples são associadas para criar funções mais complexas; (4) existe uma ordem parcial que permite o uso da programação dinâmica; (5) um conjunto de funções permitidas pode ser mantido para reduzir o tempo de execução/consumo de memória. Este trabalho apresenta algoritmos de composição funcional para fatoração Booleana, incluindo fatoração ótima, fatoração considerando o operador OU-exclusivo, computação de cadeias mínimas de decisão e síntese de funções considerando somente portas lógicas majoritárias e inversores. / This work presents functional composition (FC) as a new paradigm for combinational logic synthesis. FC is a bottom-up approach to synthesize Boolean functions, being able to evaluate the cost of intermediate sub-functions, exploring a larger number of different candidate combinations. These are interesting advantages when compared to the top-down behavior of functional decomposition. FC presents great flexibility to implement algorithms with optimal or suboptimal results for different applications. The proposed strategy presents good results for the synthesis of Boolean functions targeting different technologies. FC is based on the following principles: (1) the representation of logic functions is done by a bonded pair of functional and structural representations; (2) the algorithm starts from a set of initial functions; (3) simpler functions are associated to create more complex ones; (4) there is a partial order, enabling dynamic programming; (5) a set of allowed functions can be used in order to reduce execution time/memory consumption. This work presents functional composition algorithms for Boolean factoring, including optimal factoring, Boolean factoring considering the exclusive-OR operator, minimum decision chain computation and synthesis of functions considering only majority and inverter logic gates.

The aim of this study was to explore, describe and interpret the experiences of Immunodeficiency Human Virus (HIV) infected mothers regarding exclusive breastfeeding in the first six months of the infant’s life. This was a qualitative study with phenomenology as a design as the study was about lived experiences. The sample consisted of HIV infected mothers aged 18 years and above who opted for exclusive breastfeeding for the first six months of their infant’s lives. Purposive sampling was used. Data was collected through one to one semi structured interviews of fifteen mothers of babies aged six to twelve months. The study revealed that mothers had both positive and negative experiences which were influenced by among others; the level of support the mothers received, disclosure of HIV status and health education received at the health facility. The findings of the study revealed a low level of understanding of the Infant and Young Child Feeding Policy by health professionals / Health Studies / M. A. (Health Studies)

Jau nuo seno geografinės nuorodos savo koncepcija išsivystė kaip pirmieji prekių ženklai. Intensyvėjant bei sudėtingėjant komerciniams santykiams geografinės nuorodos ir prekių ženklai tapo skirtingomis kategorijomis žymenų, kurių registraciją, apsaugą bei naudojimą reglamentuoja intelektinės nuosavybės teisės normos. Visgi, nors tai skirtingi pramoninės nuosavybės teisės institutai, geografinės nuorodos ir prekių ženklai sutampa daugeliu aspektų. Visų pirma, šie žymenys, naudojami komercinėje aplinkoje, sutampa jiems priskirtomis funkcijomis, t.y. jie abu atlieka prekių ar paslaugų atskyrimo, kilmės šaltinio identifikavimo, kokybės identifikavimo bei vartotojų informavimo funkcijas. Be šios sutapties, geografinės nuorodos ir prekių ženklai yra panašūs, nes privalo turėti skiriamąjį požymį, o taip pat sutampa ir jų išraiškos formos bei apsaugos galiojimo laikas. Visi išvardinti panašumai, išreiškiantys ryšį tarp geografinių nuorodų ir prekių ženklų, gali lemti painiavą rinkoje bei pramoninės nuosavybės išimtinių teisių pažeidimus, todėl teisiniai mechanizmai, skirti reguliuoti šių žymenų registraciją, apsaugą ir naudojimą yra įtvirtinti siekiant išlaikyti pusiausvyrą tarp vartotojų ir gamintojų, išimtinių teisių turėtojų interesų. Numatyti teisėti geografinių nuorodų ir prekių ženklų naudotojai dėl pažeistų teisių gali remtis skirtingais būdais.

As the commercial relations become more intensive and complex, geographical indications and trade marks has become two different categories of signs, the registration, protection and usage of which is governed by the rules of intellectual property law. Nonetheless, even though geographical indications and trade marks are different institutes of industrial property law, they coincide in a majority of aspects. First of all, the fore-mentioned signs used in commercial environment coincide in the attributed functions, i.e. both of them perform the functions of distinguishing goods or services, identification of the source of origin, identification of quality and information of customers. In addition to the considered coincidence, geographical indications and trade marks are similar, since both of them must have a distinctive character; furthermore, their forms of expression and term of protection are in coincidence. All above similarities implying a relation between geographical indications and trade marks may determine confusion in the market and infringements of the exclusive rights of industrial property; therefore, legal mechanisms intended for the regulation of the registration, protection and usage of the considered signs have been established to keep the balance between the interests of customers and producers and holders of exclusive rights.

The thesis is devoted to the study of diffractive physics with the ATLAS detector at the LHC. After a short introduction to diffractive physics including soft and hard diffraction, we discuss diffractive exclusive production at the LHC whichis particularly interesting for Higgs and jet production. The QCD mechanism described by the Khoze Martin Ryskin and the CHIDe models are elucidated in detail. The uncertainties on these models are still large and a new possible exclusive jetmeasurement at the LHC will allow to reduce the uncertainty on diffarctive Higgs boson production to a factor 2 to 3. An additional measurement of exclusive pion production pp ! p_+_−p allows to constrain further exclusive model relying on theuse of the ALFA stations, which are used in the ATLAS Experiment for detection of protons scattered in elastic and diffractive interactions. In the last part of the thesis, the AFP detectors, aiming at measuring the protons scattered in diffractive interactions, are presented. They allow to extend substantially the ATLAS physics programme. In particular, the study of the central diffractive W boson production process makes possible a better determination of the nature of diffractive exchanges.

Objective: The aim of this study was to investigate if the head circumference of stunted quilombolas children differs from that other children with adequate linear growth and if the insufficient birth weight and exclusive breastfeeding in the first month of life intervene with this relation. Methods: The work followed a transversal studying involving all the children of 12 to 60 months (n=725) pertaining to the quilombolas community of Alagoas (n=39). Variables demographics, socioeconomics, of the health and anthropometrics indices had been collected. These had been compared with the curves of the standard of reference of the of WHO 2006. The children had been categorized into two groups in agreement with the presence or not of the malnutrition (stunted/eutrophic), diagnosed by means of the height deficit (height-for-age < -2,0 SD). Each group was divided in two sub-groups agreements the insufficient birth weight (IBW < 3000g). Finally, each sub-group formed two other categories according to the exposition or not to the exclusive breastfeeding in the first month of life (breastfeeding/ not breastfeeding). Thus, eight groups of studies were formed, which, for the statistics analysis, had been expresses as ordinary category variables (1 a 8), group 1 was formed for the children submitted to worst conditions (undernutrition, with IBW and that weren t to breastfed) and group 8 for the best ones (eutrophic with adequate birth weight and that was to breastfed). The average of the head circumferencefor- age (HC) was compared using ANOVA and the Turkey test as pos-hoc. For this, group 8 was assumed as control. To investigate the principal risk factors associated to the occurrence of the deficit of HC (z < 1.5), regression logistic analyze was used, remaining in the last model the independent variables which associations presented p<0.05. Results: The prevalence of nutritional deficits for indicators height-for-age, weight-forage, weight-for-height and head circumference-for-age was respectively of 10.8%, 1.9%, 1.3% e 10.5%. The overweight (weigh-for-age > 2 SD) represents 6.4%. The averages of Z-score of the head circumference for the groups 1, 2, 3, 4, 5, 6, 7 e 8 was -1.67*, -1.09, - 0.97, -0.94, -1.02, -0.69, -0.68 e -0.53 respectively. Group 1 was the unique that presented statistics differences (p< 0,05) compared to the control group, suggesting the protective role of breasting against reduction of the HC, when the presence of the chronic malnutrition (express for height deficit) in children that were born with IBW, because the exposition to exclusive breastfeeding was the unique differential used on the formation of the groups 1 and 2. On the multivaried analyzis, the factors that were significantly associated to deficit of HC were the stunted, the insufficient birth weight, the feminine sex and the increase of chronological age in one month increase the chances of occurrence these outcomes in 119%, 77%, 63% e 2% respectively. But the increase of time of the exclusive breastfeeding in one month reduces the possibilities in 10%. Conclusions: The children who are stunted, are born with insufficient weight and that they had not been was exposed to exclusive breastfeeding for one month, demonstrate consistently the worst averages of Z-score of head circumference when compared to children not submitted to stress . In this context, the exposition of breastfeeding per for one month possibly, of the central nervous system. Although traditional population have been considered, the average time of the exclusive breastfeeding was behind of the praised for the WHO. Thus, it was suggested the more investments on the direction of the increase the period of the exposition to exclusive breastfeeding between the quilombolas children of the Alagoas state. / Objetivo: Investigar se o perímetro cefálico de crianças quilombolas com déficit estatural difere daquela observado em crianças com crescimento linear adequado e se o peso insuficiente ao nascer e o aleitamento materno exclusivo no primeiro mês de vida interfere nessa relação. Métodos: Estudo transversal envolvendo todas as crianças de 12 a 60 meses (n=725) pertencentes às comunidades quilombolas (n=39) de Alagoas. Coletaram-se dados demográficos, socioeconômicos, de saúde e antropométricos. Estes foram comparados às curvas do padrão de referência da OMS-2006. As crianças foram categorizadas em 2 grupos conforme a presença ou não da desnutrição (desnutrida/eutrófica), diagnosticada por meio do déficit estatural (estatura-para-idade < - 2,0 desvio-padrão). Cada grupo foi subdivido em 2 sub-grupos conforme o Peso Insuficiente ao Nascer (PIN < 3000g). Finalmente, cada sub-grupo formou duas outras categorias segundo a exposição ou não ao aleitamento materno exclusivo por 30 ou mais dias (mamou/não mamou). Assim, formaram-se oito grupos de estudos, os quais, para a análise estatística, foram expressos como variáveis categóricas ordinais (1 a 8), de modo que o grupo 1 fora formado pelas crianças submetidas às piores condições (desnutridas, com PIN e que não mamaram) e o grupo 8 pelas melhores (eutróficas, com peso adequado ao nascer e que mamaram). A média do perímetro cefálico-para-idade (PC) foi comparada utilizando ANOVA e o teste de Tukey como pos-hoc. Para isso, assumiu-se o grupo 8 como controle. Para investigar os principais fatores de risco associados à ocorrência do déficit de PC (z < -1,5), utilizou-se a análise de regressão logística, mantendo-se no modelo final as variáveis independentes cujas associações apresentaram p<0,05. Resultados: As prevalências de déficits nutricionais para os índices altura-para-idade, peso-para-idade, peso-para-altura e PC foram, respectivamente, 10,8%, 1,9%, 1,3% e 10,5%. O sobrepeso (peso-para-altura > 2 DP) representou 6,4%. As médias de escore Z do perímetro cefálico para os grupos 1, 2, 3, 4, 5, 6, 7 e 8 foram -1,67*, -1,09, -0,97, -0,94, - 1,02, -0,69, -0,68 e -0,53, respectivamente. O grupo 1 foi o único que apresentou diferença estatisticamente significativa (p < 0,05) em relação ao grupo controle, sugerindo um papel protetor do aleitamento materno contra a redução do PC, quando da vigência da desnutrição crônica (expressa pelo déficit estatural) em crianças nascidas com PIN, haja vista que a exposição ao aleitamento materno foi o único diferencial utilizado na formação dos grupos 1 e 2. Na análise multivariada, os fatores que se apresentaram significativamente associados ao déficit de PC foram o déficit estatural, o PIN, o sexo feminino e o aumento da idade cronológica em um 1 mês, as quais, elevaram as chances de ocorrência desse desfecho em, respectivamente, 119%, 77%, 63% e 2%. O aumento do tempo de aleitamento materno exclusivo em um mês, reduziram essas chances em 10%. Conclusões: As crianças que apresentam baixa estatura, nascem com peso insuficiente e que não foram expostas ao aleitamento materno exclusivo por pelo menos 1 mês apresentam menores valores de perímetro cefálico, quando comparadas a crianças não submetidas a esses estresses. Nesse contexto, a exposição ao aleitamento materno exclusivo por 30 ou mais dias constitui-se num importante fator de proteção, no sentido de preservar o crescimento do perímetro cefálico e possivelmente, do sistema nervoso central. Apesar de tratar-se de uma população dita tradicional, o tempo médio de aleitamento materno exclusivo ficou aquém do preconizado pela OMS. Diante desses resultados, sugere-se maiores investimentos no sentido de aumentar entre as crianças quilombolas de Alagoas, o período de exposição ao aleitamento materno exclusivo.

The first two chapters analyze the economic effects of privately informed lobbying applied to tariff protection (Chapter 1) and to customs unions agreements (Chapter 2). The third chapter investigates the choice of retailing strutures when principals (the producers) are privately informed about their production costs. Chapter 1 analyzes how lobbying affects economic policy when the interest groups have private information. I assume that the competitiveness of producers are lobbies private information in a Grossman and Helpman (1994) lobby game. This allows us to analyze the e¤ects of information transmission within their model. I show that the information transmission generates two informational asymmetry problems in the political game. One refers to the cost of signaling the lobby's competitiveness to the policy maker and the other to the cost of screening the rival lobby's competitiveness from the policy maker. As an important consequence information transmission may improve welfare through the reduction of harmful lobbying activity. Chapter 2 uses the framework of chapter 1 to study a customs union agreement when governments are subject to the pressure of special interest groups that have better information about the competitiveness of the industries they represent. I focus on the agreement's effect on the structure of political influence. When join a customs union, the structure of political pressure changes and with privately informed lobbies, a new effect emerges: the governments can use the information they learn from the lobby of one country to extract rents from the lobbies of the other country. I call this the 'information transmission effect'. This effect enhances the governments'bargaining power in a customs union and makes lobbies demand less protection. Thus, I find that information transmission increases the welfare of the agreement and decreases tari¤s towards non-members. I also investigate the incentives for the creation of a customs union and find that information transmission makes such agreement more likely to be politically sustainable. Chapter 3 investigates the choice of retailing structure when the manufacturers are privately informed about their production costs. Two retailing structures are analyzed, one where each manufacturer chooses her own retailer (exclusive dealing) and another where the manufacturers choose the same retailer (common agency). It is shown that common agency mitigates downstream competition but gives the retailer bargaining power to extract informational rents from the manufacturers, while in exclusive dealing there is no downstream coordination but also there are no incentives problem in the contract between manufacture and retailer. A pre- liminary characterization of the choice of the retailing structure for the case of substitute goods shows that when the uncertainty about the cost increases relatively to the size of the market, exclusive dealing tends to be the chosen retailing structure. On the other hand, when the market is big relatively to the costs, common agency emerges as the retailing structure. This thesis has greatly benefited from the contribution of Professors Humberto Moreira and Thierry Verdier. It also benefited from the stimulating environment of the Toulouse School of Economics, where part of this work was developed during the year of 2007. / Esta tese consiste de três artigos que tem como elemento unificador o modelo de agência comum com principais informados. Os dois primeiros capítulos investigam os efeitos econômicos da influência de grupos de pressão (lobbies) sobre a escolha da tarifas de importação (Capítulo 1) e sobre acordos de comércio internacionais (Capítulo 2). O capítulo 3 investiga a escolha da estrutura de revenda quando os produtores possuem informação privada sobre os seus custos. O capítulo 1 analisa como a atividade de lobby afeta a política econômica quando grupos de interesses possuem mais informação que o governo. Modifica- se o modelo de Grossman e Helpman (1994), assumindo que a competitividade dos produtores é informação privada dos lobbies. Isto permite investigar quais os efeitos de transmissão de informação neste modelo. Esta assimetria de informação gera dois efeitos no jogo político, um associado ao problema de sinalização da competitividade do lobby para o governo e outro associado ao custo de um lobby fazer um screening da competitividade do lobby rival junto ao governo. O principal resultado deste modelo é que a transmissão de informação reduz a capacidade de influência dos lobbies, o que aumenta o bem-estar da sociedade. O capítulo 2 aplica o modelo do Capítulo 1 para entender os efeitos de transmissão de informação que surgem em uniões aduaneiras quando os lobbies possuem mais informação que o governo. O foco é dado nos efeitos políticos que surgem nestes acordos. Quando os países formam uma união aduaneira o equilíbrio de forças político e um novo efeito surge: os governos usam as informações privadas do lobby de um país para extrair renda dos lobbies dos outros países. Este efeito aumenta o poder de barganha dos governos dentro de uma união aduaneira e reduzam a capacidade de influência dos lobbies. Desta forma, a transmissão de informação aumenta os benefícios de uma união aduaneira e reduz a tarifas de importação para os países fora do acordo. Além disso, é investigado o papel da transmissão de informação a criação das uniões aduaneiras e o resultado encontrado é que esta aumenta as chances destes acordos serem implementados. O capítulo 3 investiga a escolha da estrutura de revenda quando os produtores possuem informação privada sobre seus custos de produção. Duas estruturas de revenda são analisadas, uma onde cada produtor escolhe um revendedor exclusivo (exclusive dealing) e outra onde ambos os produtores escolhemo mesmo revendedor (agência comum). Agência comum reduz a competição no mercado final, mas dá ao revendedor a capacidade de extrair lucro dos produtores utilizando a informação de um contra o outro. Enquanto que exclusive dealing aumenta a competição entre produtores, mas não cria problemas informacionais entre produtor e revendedor. Uma caracterização preliminar da escolha da estrutura de revenda para o caso de bens substitutos mostra que quando a incerteza quanto sobre o custo aumenta relativamente ao tamanho do mercado, exclusive dealing tende a ser a estrutura de revenda escolhida, enquanto que quando o tamanho do mercado é grande em relação aos custos, agência comum tende a ser a estrutura escolhida. Esta tese se beneficiou enormemente da contribuição dos professores Hum- berto Moreira e Thierry Verdier. Também se beneficiou o estimulante ambiente acadêmico da Toulouse School of Economis, onde parte dela foi desenvolvida du- rante o ano de 2007.
